References, like pointers, are a language feature you must be able to utilize with ease. Many other languages use references for indirect addressing without requiring the thorough understanding that C++ imposes to correctly utilize both pointers and references. Just as with pointers, you will see references frequently used throughout code from other programmers. You may be pleased that using references ...
